At startup, I load MEGABYTES of external code (IMO, Emacs UI is
untolerable without a lot of tweaking - at least it was a decade ago,
when my configuration got more or less frozen).  Some of it is written
by me, but most is other people code.  So I base my judgement not only
on my code - although "the other code" is also "chosen by me", so might
be not very representative. ;-)

This is not the first (and maybe even not the third :-() time Emacs
breaks compile.el.  Which means that REx engine can't even handle
quite primitive RExen.  I would have expected that already on the
first time these would become items of the test suite...
